UNITED STATES PATENT OFFIc CHARLES P. HOLMES, GOUVERNEUR, NEW YORK.

RAILWAY-CAR-AXLE LUIBRICATOR.

SPECIFICATION forming part of Letters Patent No. 278,964, dated June 5,1883. Application filed February 27, 1883. (No model.)

To all whom it may concern Be it known that I, CHARLES P. HoLMEs, ofGouverneur, in the county of St. Lawrence and State of New York, haveinvented certain new and useful Improvements in Rai1way-0ar- AxleLubricators; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, which forms a part ofthis specification.

My invention has relation to that class of lubricators forrailway-caraxles which consists of two rollers fixed upon opposite endsof a common tubular shaft, which is provided with a feed-chain dippingin an oil-reservoir located in the bottom of the journal-box; and itconsists in an improvement upon the lubricating device for which LettersPatent of the United States No. 273,991 were granted to me on the 13thday of March, 1883, which said improvement will be hereinafter morefully described and claimed, reference being had to the drawing heretoattached, in which I have shown a longitudinal sectional view of myimprovement.

My improved lubricating device consists of a tubular shaft, B, the endsof which are formed with annular flanges, (shown at b.) The middle partof the shaft is swelled to form ribs 0, midway bet-ween the end rollers,A A. The latter are made of the material known in commerce as vulcanizedfiber or vulcanized paper, which is compressed in suitable dies or moldsand afterward finished by turning in a lathe to make them perfectlytrue. In shape these rollers do not differ from the metallic rollersshown and described in my Patent No.

vulcanized rubber are not new.

These ribs, formingpart of the metallic shaft B, are not easily worn by the links of theendless feed-chain passing over it, as would be the case if they weremade of the same material as the rollers. On the other hand, the rollersA A will not, as metallic rollers, in'course of time indent or groovethe journal against which they bear, but will leave this uninjured, nomatter at how great a speed the train is run. I have also found thatthese rollers feed the oil better and more evenly than metallic rollers.

I am aware that lubricating-rollers made of Neither do I claim suchrollers, broadly; but

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

The improved lubricating-roller for railwaycar axles herein shown anddescribed, consisting of the central tubular shaft, B, having endflanges, b, and central ribs, a, and a pair of rollers, A A,ofvulcanized fiber, fixed upon op posite ends of the flanged shaft andimpinging on their inner sides against the ribs a, substantially as andfor the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereuntoaffixedmy signature in presence of two witnesses.
